Abstract
An electronic device includes at least one processor, a first storage unit configured to store a secret value set by a host, a second storage unit configured to store a boot loader code, a first firmware code, and a second firmware code, and a read-only memory (ROM) configured to store a ROM code executable in a booting operation. The ROM code, when executed, may cause the at least one processor to generate a first booting value based on the secret value and a first hash value for the boot loader code, the boot loader code, when executed, may cause the at least one processor to generate a second booting value based on the first booting value and a second hash value for the first firmware code, and the first firmware code, when executed, may cause the at least one processor to generate a third booting value based on the second booting value and a third hash value for the second firmware code.
